Soap catcher & cup holder for laundry detergent bottles. Fits around 1.7" spout (for the big jugs of detergent) and holds a cup around 2" diameter under the spout.
Let me know in the comments if it doesn't fit your laundry bottle. I keep uploading new designs with the opening a bit bigger as I make more for friends and sand them down.
Printed in ABS originally.
Fit and function
If it's too tight then sand it down but you want it to stay on nicely. If it's too loose add some tape around your cap or remix the model.
